DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figures 1 to 3 A construction concrete maintenance spraying device comprises a bottom plate 1, a motor 5 is arranged on the bottom plate 1, a mounting shaft 7 is fixedly installed on the shaft output end of the motor 5, two fixing plates 8 are fixedly installed on the mounting shaft 7, a connecting ring 9 is fixedly installed on the two fixing plates 8, a hollow cylinder 10 is arranged between the two connecting rings 9, and positive spray heads 11 are evenly and evenly inlaid on the hollow cylinder 10;

[0026] The hollow cylinder 10 is rotatably mounted on the connecting ring 9. This rotatable mounting can keep the angle of the hollow cylinder 10 stable through the cooperation of the threaded groove with the screw, gear and tooth groove and other structures. Since it is a prior art, it is not described in detail. The rotation of the hollow cylinder 10 can change the injection angle of the front nozzle 11, thereby making it more applicable.

[0027] When the motor 5 rotates, the mounting shaft 7 drives the two fixing plates 8 to rotate, and then the connecting ring 9 and the hollow cylinder 10 thereon can rotate, and the height of the front nozzle 11 also changes accordingly. The height of the front nozzle 11 can be adjusted according to the actual situation.

[0028] The two fixing plates 8 are both hollow structures, and the side of the two fixing plates 8 facing away from the water tank 4 are evenly and evenly inlaid with side nozzles 12 equidistantly installed.

[0029] The side spray heads 12 on the two fixed plates 8 can spray the vertical wall or slope synchronously, thereby reducing the manual workload.

[0030] A threaded rod 21 is rotatably installed inside the two fixed plates 8, and a nut pair 22 is threadedly connected to the threaded rod 21. A movable plate 23 is fixedly installed on the nut pair 22. When the threaded rod 21 is rotated, the nut pair 22 moves on the threaded rod 21, and the movable plate 23 moves synchronously, so that the volume of water that can be accommodated inside the fixed plate 8 changes, and thus the number of side nozzles 12 that can be normally sprayed on the fixed plate 8 changes, so that the equipment can be suitable for vertical plane spraying activities at different heights.

[0031] The movable plate 23 fits with the inner wall of the fixed plate 8, a transverse bevel gear 20 is fixedly installed on one end of the threaded rod 21, a vertical bevel gear 19 is rotatably installed at the corresponding position of the fixed plate 8, a connecting rod 13 is fixedly installed at the center of the vertical bevel gear 19, and the connecting rod 13 passes through the fixed plate 8 and is fixedly installed with a hand wheel 18.

[0032] When the hand wheel 18 is turned, the vertical bevel gear 19 rotates synchronously through the connecting rod 13, and the vertical bevel gear 19 is engaged with the transverse bevel gear 20, so the transverse bevel gear 20 rotates, and the rotation of the transverse bevel gear 20 drives the threaded rod 21 to rotate, and the moving plate 23 moves.

[0033] A sealing ring 24 is embedded and installed on the movable plate 23 , and the sealing ring 24 is interference fit with the gap between the movable plate 23 and the fixed plate 8 .

[0034] The presence of the sealing ring 24 prevents water from invading, so that the interior of the fixing plate 8 is divided into two parts, one filled with water and the other not filled with water.

[0035] The two fixed plates 8 are provided with observation windows 14 for observing the position of the movable plate 23. The observation windows 14 are made of transparent material and are used to observe the ground position valve, so as to know which side nozzles 12 can spray normally.

[0036] A water tank 4 and a water pump 15 are provided on the bottom plate 1 , and the water tank 4 and the water pump 15 are connected via a connecting pipe 6 . A main delivery pipe 16 is embedded and installed at the output end of the water tank 4 , and the other end of the main delivery pipe 16 is fixedly installed on the hollow cylinder 10 .

[0037] A side delivery pipe 17 is embedded and installed on the output end of the water tank 4. There are two side delivery pipes 17, which are respectively connected to the fixed plates 8 on both sides. The two side delivery pipes 17 can be opened and closed independently.

[0038] The water inside the water tank 4 is transported to the water pump 15 through the connecting pipe 6, and then transported to the hollow cylinder 10 and the fixed plate 8 through the main delivery pipe 16 and the side delivery pipe 17 for temporary storage, and then sprayed out through the front nozzle 11 and the side nozzle 12 to achieve a spraying effect.

[0039] A universal wheel 2 is fixedly mounted on the bottom of the base plate 1, and a push plate 3 is fixedly mounted on the side of the base plate 1. The existence of the push plate 3 enables the device to be moved to a desired position simply and quickly.

[0040] The working process of the utility model is as follows: firstly, the device is moved to a suitable position, and then the nozzle 11 is adjusted according to the actual height requirements and angle requirements.

[0041] When the motor 5 rotates, the connecting pipe 6 drives the two fixing plates 8 to rotate, and then the connecting ring 9 and the hollow cylinder 10 thereon can rotate, and the height of the front nozzle 11 also changes accordingly. The height of the front nozzle 11 can be adjusted according to the actual situation.

[0042] By rotating the hollow cylinder 10 on the connecting ring 9 , the spray angle of the front nozzle 11 can be changed.

[0043] Afterwards, the water in the water tank 4 is transported to the inside of the water pump 15 through the connecting pipe 6, and then transported to the inside of the hollow cylinder 10 through the main transport pipe 16, and through the front nozzle 11, the spraying effect of the concrete floor is achieved.

[0044] When the equipment is in a position vertical to the wall, the corresponding side delivery pipe 17 is opened as needed, and then adjusted according to the height of the wall, the hand wheel 18 is turned, and the vertical bevel gear 19 rotates synchronously through the connecting rod 13, and the vertical bevel gear 19 is engaged with the horizontal bevel gear 20, so the horizontal bevel gear 20 will rotate, and the rotation of the horizontal bevel gear 20 drives the threaded rod 21 to rotate, and the movable plate 23 then moves, and the movable plate 23 moves synchronously, and then the volume of water that can be accommodated inside the fixed plate 8 changes, so that the number of side nozzles 12 that can be normally sprayed on the fixed plate 8 changes, and the equipment can be suitable for vertical plane spraying activities at different heights.

[0045] After use, the fixing plate 8 can be placed in a vertical position relative to the bottom plate 1, thereby effectively reducing the floor space of the device and facilitating storage.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
